Application filed April 29, 1910. Serial No. 558,328.

To all whom it 'may concern:

Be it known that I, CHOICE I-I. KELLEY, a citizen of the United Statesof America, residing at Fullerton, in the parish of Vernon and State ofLouisiana, have invented new and useful Improvements in Log-Loadingrlongs, of which the following is a specilication.

This invention relates to tongs to be utilized in handling and loadinglogs, and it has for its object to produce a device 'of this class whichshall possess superior advantages in point of simplicity, durability andgeneral eliiciency.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination Iof partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention be resorted to when desired.

In the drawing-Figure 1 is a front elevation, showing a log to which theimproved loading tongs have been applied. Fig. 2 is a perspective detailview of one of the jaw members of the tongs. Fig. 3 is a sectionaldetail view taken through the toothed portion vof the jaw member. Fig. Lis an end view of the jaw member. Fig. 5 is a erspective detail view ofthe detachable tooth, showing the same detached from the jaw member.

Corresponding parts in the several figures are denoted by likecharacters of reference.

Log loading tongs usually consist of two jaw members which are connectedby a chain or chains with a link at one end of a flexible hoistingelement, such as a rope or cable, which may be guided over a suitablyarranged pulley to a hoisting mechanism, such as a motor-driven windingdrum, whereby strain may be applied to lift the log. In Fig. 1 of thedrawings a pulley 1 has been shown, the same serving as a guide for theflexible hoisting element 2 having a link 3 which is connected by chains4, i with the jaw members B, B, which latter constitute the presentinvention. Each of said jaw members comprises a body portion 5 having aslightly inclined arm 6 extending laterally from the upper end thereof,said arm being provided with a terminal aperture 7 to enable it to bereadily connected with one of the chains t. At its lower end the bodyportion 5 is provided with a laterally extending elbow 8, the face ofwhich is provided with integral sharp-pointed triangular or wedge-shapedteeth 9 at the said teeth surrounding a recess 10 having ascrew-threaded socket 11 for the recept-ion of the exteriorly threadedshank 12 of a detachable tooth 13, which latter is of polygonal ornon-circular cross section, so that a suitably constructed wrench may bereadily applied thereto for the purpose of tightening it in position.The detachable tooth 13 is of a length exceeding that of the teeth 9, aswill be very clearly seen by reference to Fig. 3 of the drawings.

When the jaw members B are applied to the ends of a log, as shown inFig. 1, the log will be rst engaged by the projecting end of the tooth13 which by a slight stroke of a hammer or mallet may be driven into theend of the log until the latter is engaged by the teeth 9; or the arm 6may be held and utilized as a handle while the toothed end of the jawmember is driven into engagement with the log. When strain is exercisedupon the chains t, the teeth 9 will lirmly grip the ends of the log,preventing the latter from turning or from becoming detached ordisplaced in the act of lifting and handling, it being especially notedthat the teeth 9 adjacent to the lower edges of the jaw members willpositively and unfailingly engage and grip the log when the jaw membersare tilted by upward stress upon the chains 1, thus positively holdingthe log and preventing it from rotating about its axis.

The improved device, as will be seen from the foregoing description, isextremely simple in construction and easily applied or detached, and ithas been found to be thoroughly etlicient for the purposes for which itis provided.

I-Iaving thus described the invention, what is claimed as new, is

In a device of the character described, a jaw member including a bodyportion having at one end a lateral extension constituting a handle andat the other end an elbow provided with a recess and with integralsharp-pointed teeth, two such teeth being formed adjacent to the twosides of the recess and a third tooth being formed adjacent to the loweredge of the recess, said elbow being also provided with a screw threadedsocket; in combination with an auxiliary tooth of greater length thanthe integral teeth, said auxiliary tooth being of polygonal Crosssection to constitute a wrench seat, and said auxiliary tooth beingprovided with a threaded shank engaging the socket, whereby saiddetachable tooth is mounted between the teeth at the sides of the recessand above the tooth at the lower edge of the recess. 15

In testimony whereof I aX my signature in presence of two witnesses.
